Sigimund

Sigimund (died 271 AD) was the chief of the Germanic Buri tribe of southern Poland during the late 3rd century AD. He was an archenemy of the Roman Empire during the Crisis of the Third Cenutry, conquering parts of Dacia before being slain at the Battle of Tismanum.

Biography
Sigimund was born in Grinev in the lands of the Germanic Lugii tribe in what is now Bohemia and Moravia, and he was raised as a warrior. He became king of his people during the late 3rd century AD, and he took advantage of the Roman Empire's internal strife to invade Roman lands during the Crisis of the Third Century. In 271 AD, his massive army captured the Dacian provincial capital of Zarmizegetusa, a humiliation to the Romans. Emperor Aurelian dispatched Legio IV Pannonica to recapture the city, but Sigimund led his army of over 2,400 warriors to attack the 1,400-strong Roman legion halfway between Drobeta and Zarmizegetusa at Tismanum (now Tismana, Romania). In the ensuing battle, the Roman cavalry outflanked the Buri warriors as they engaged in melee combat with the Roman infantry, and he and his warriors were encircled during his army's retreat. Sigimund and his men fought to the last, dying in the heat of battle. The remnants of the Buri were forced to retreat back to Grinev, and the Romans were able to focus on the Quadi threat.
